Apple has introduced a security measure in macOS Mojave (10.14) and newer that is a requirement for some third-party updates. macOS uses the Microsoft AutoUpdate for patching Microsoft Office applications which is the Microsoft supported mechanism for this OS.
The Automox agent (amagent) now leverages Microsoft AutoUpdate for patching Microsoft Office on devices running on macOS. Click OK when macOS prompts you for the security approval for the Automox agent to access Microsoft AutoUpdate. You will only need to do this one time.
